Commit Message

Arnd Bergmann Jan. 26, 2023, 9:17 p.m. UTC 
From: Arnd Bergmann <arnd@arndb.de>

The newly added MSI support is mostly hidden inside of an #ifdef,
except for one line that now causes a build failure when MSI
is disabled:

drivers/ufs/host/ufs-qcom.c: In function 'ufs_qcom_remove':
drivers/ufs/host/ufs-qcom.c:1698:9: error: implicit declaration of function 'platform_msi_domain_free_irqs' [-Werror=i]
 1698 |         platform_msi_domain_free_irqs(hba->dev);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Above that, the symbol that guards the other call was recently
removed, so that is all dead code at the moment.

Remove the incorrect #ifdef and instead of a Kconfig dependency
to only allow building the driver when CONFIG_GENERIC_MSI_IRQ
is enabled. This symbol is always present when PCI_MSI
or ARM_GIC_V3_ITS are enabled, both of which should be present
on kernels that can run on Qualcomm SoCs.

The 'select RESET_CONTROLLER' in combination with this dependency
unfortunately causes a dependency loop and this is a user-visible
symbol, so it's better to change both to 'depends on'.

Fixes: 519b6274a777 ("scsi: ufs: qcom: Add MCQ ESI config vendor specific ops")
Fixes: 13e7accb81d6 ("genirq: Get rid of GENERIC_MSI_IRQ_DOMAIN")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
---
Not sure if this is the best solution, both the GENERIC_MSI_IRQ
dependencies and the RESET_CONTROLLER dependencies are a bit
inconsistent already. Feel free to pick another approach that
addresses both of the bugs I found.

I think your proposed solution works best at the moment.

Thank you for pointing to 13e7accb81d6 ("genirq: Get rid of 
GENERIC_MSI_IRQ_DOMAIN"),

which I was not aware of. I am thinking about fixing it just like how

13e7accb81d6 ("genirq: Get rid of GENERIC_MSI_IRQ_DOMAIN") is fixing 
drivers/dma/qcom/hidma.c -

In ufs-qcom.c, use CONFIG_GENERIC_MSI_IRQ instead of 
CONFIG_GENERIC_MSI_IRQ_DOMAIN,

and meanwhile add #ifdef check before calling 
platform_msi_domain_free_irqs().

Please let me know your idea.


Thanks.
Regards,
Can Guo

No. Let's get rid of the ifdef's please... I like Arnd's patch as it models the
dependency nicely in Kconfig. And most (all?) of the qcom platforms require
GENERIC_MSI_IRQ and RESET_CONTROLLER one way or the other anyway.

Make sense, I agree.
